A NACHI-proprietary semi-circular bar-rel swash plate that receives pressure on its surface ensures a stable dis-charge volume at all times. This elimi-nates excess discharge volume, and enables the ef-fective use of power corresponding to the load cycle.
This "energy-saving type" conserves energy, reduces power loss, and helps to reduce hydraulic costs.
Use flexible couplings for connecting the pump shaft to the drive shaft, and prevent a radial or thrust load from being applied on the pump shaft.
For centering of the pump shaft, limit the eccentricity between the drive shaft and hydraulic pump shaft to 0.05 mm, and keep the angle error within 1°.
